not FFM, but i have tried 'droid 2.2 with built in browser (what is it? modified opera, or chrome?) - it worked!!
i can guess 1 of 2 obvious things:
new browser fixes issues/includes support
cookies issue - maybe try clearing cookies?
i did wipe my phone prior to droid2.2 install so nothing at all was used/found from the 2.1 install.
